MANUFACTURE OF YARNS OR THREADS Filed June 13 1952 Patented Feb. 21, 1933 NORMAN GROSSLEY, or nunnnasrintn} ENGLAND MANUFACTURE or Ynnns on 'r nannns Application filed .Tune 13, 1932, Serial No. 616,975, and in Great Britain March 4, 1931.

An application for patent on said improvements was filed in Great Britain on Mar. 4, 1931, Serial No. 6,650.

This invention relates to apparatus for '5 use in the manufacture of yarns or threads comprising rings or. cores of fibrous sub-.'

stances of a springy or elastic nature, such for example as hair, or the like, which are encircled or bound into a thread by winding around them a'binding or retaining thread, and the present" invention has for its object to introduce an improved construction of yarn or thread of this type and also of mechanism for manufacturing it.

5 For this purpose the fibrous substance in the form of a slightly twisted roving or core with or without a carrying thread is caused to pass through a revolvingiunnel formed at the top of a tubular spindle through which the twisted roving or core passes, a binding yarn being'wound around the core by means of a yarn carrier which is detachably and rotatably mounted on the spindle and takes the binding yarn from a cop,

bobbin, or cheese that is rotatably mounted on the spindle.

According to this invention a metal tapered sleeve forms a permanent fitting on the tubular spindle and is rotatable thereon and adapted to receive a tapered tube on which the binding yarn is wound, a yarn carrier preferably being detachably and rotatably mounted on the spindle for wrapping the binding yarn around the slightly twisted roving, or core. I

A preferred construction of yarn carrier comprises an eyelet fixed to or forming a part of a ball bearing that is detachably secured to the spindle in such a manner that it can be readily removed for the replacement oi a cardboard or other tapered tube that fits on the metal tapered sleeve and carries the cheese or other supply of binding yarn.

In the accompanying drawing a a a I Fig. l is an elevation partly in section of revolving spindle apparatus constructed in accordance with this invention for use in the manufacture of yarns or threads of the kind specified.

Fig. 2 is a plan of the revolving carrier for the binding yarn.

.. 'indica '55 ces the revolving tubular spindle,

B the twisted roving which passes through it,'(] the binding yarn, D the revolving yarn carrier, and E the metal tapered sleeve. In the example shown the tubular spindle A'is rotatably mounted in a ball bearing a in a bracket (4 that'is bolted to a railF on the machine frame. The upper part of the tubular spindle A. terminates in a funnel a which is situated, in proximity to a pair of drawing rollers not shown. This tunnel may have a bar extending across its mouth through diametrically arranged holes a and such bar may have a diamond shaped boss in the centre to shake the fibrous substance and prevent it from running continuously in one position, or the bar may be dispensed with. Rotatably mounted on the tubular spindle A is the tapered metal sleeve E which forms a permanent fitting on-the spindle and is retained in position thereon by a spring retaining ring ewhich is sprung into a groove 6 in the tapered sleeve and exerts pressure upon balls 6 which project through holes formedin the sleeve and enter an annular groove a formed in the tubular spindle A. The end portion of the tapered sleeve E that occupies a position between the ends of the retaining ring 6 may be indented ,7 to prevent the retaining ring from turning round in its groove. The pressure that the retaining ring a exerts upon the balls 6 may be used for regulating the amount of friction that exists between the tapered sleeve E and the spindle A. The upper end of the tapered sleeve E with the retaining ring and ball friction device occupy a position in a cavity a formed in the underside of the bracket a so as to be out of the way of flufl that collects during the running of the machine. The binding yarn C is wound in the form of a cheese 0 on a paper or other perforated tube 0 which is pressed on to the tapered metal sleeve E. The yarn carrier D comprises an eyelet-formed in a piece of Wire that is fixed to the outer ring d of a ball from the first spindle apparatus assin bear-in of which the inner ring d fits'on a through the second one and being su jecte reduc portion of the spindle A and is reto a second lapping operation in the oppotained in position by a tubular screw d which site direction after issuing through the spin- 5 is screwed into the end of the spindle A. dle and. means whereby the second spindle 7 The eyelet of the yarn carrier comprises a apparatus can be moved out of linewith the coil whieh i twi md th t th yarn t first spindle apparatus for enablizg the matically threads itself when allowed to mpty spool tobe removed and replac with come in contact with the eyelet during the a ill one.

The second apparatus is mounted in a similar I manner to the first one on a bracket a. The latter-is loosely mounted on a square portion a that is clamped to an extension a of the I brackets by a'screw a. The bracket a r y M can be fixed in its operative position 'on the square portion a by a hand screw a. When the latter is slackened the bracket a" can be lifted above the square portion a and turned out of line with the upper spindle apparatus for enabling the tube c to be removed when empty and replaced by one carrying a cheese 0 of binding thread.

What I- claim as my invention and desire to secure by Letters Patent in the United 9 States is:--- p a 1. In spindle apparatus for winding a binding thread around a core of fibrous substance, the combination of a positively driven tubular spindle, a sleeve rotatably mounted on the spindle and driven by frictional contact with the spindle, means for retaining the sleeve in position on the spindle the said means comprising an annular groove formed in the spindle holes formed in the sleeve,

balls situated in the holes and a spring retaining ring encircling an annular groove on the sleeve and arranged to exert pressure on the balls, a yarn carrier detachably mounted on the sleeve and a thread guide rotatably and detachably mounted on the spindle and pulled around by the binding yarnas the latter is pulled off the spool.
